[Prior art]
Conventionally, as a device that cuts and separates the ends, such as the roots, rhizomes, and leaf tips of agricultural products such as leeks and sea cucumbers, a conveyor having a plurality of V-shaped cross-section receiving members attached at a predetermined pitch. A device for a leek that has a structure in which a rotary blade is provided on the side part of the conveyance path of the leek, and a leek is placed on the receiving member one by one, and the root or the leaf tip or both are continuously cut with the rotary blade while being conveyed. It was known.
In this conventional apparatus, since the length of the end to be cut changes depending on the position where the leeks of the receiving member are placed, in order to cut and align at a certain place, visually check that the ends are aligned at the same position one by one. The workability was not so good because it was necessary to put it on the receiving member while matching. In addition, even when the root part of the leek is bent with respect to the leaves and stems, it can not be cut correctly at right angles with respect to the root part, except for being placed on the receiving member and cutting as it is straight. The cut surface was slanted. When the cut surface is slanted, there are many problems such as roots remaining partially (see FIG. 7) and conversely cutting too deeply (see FIG. 8). Especially in the case of leeks, if the roots are cut too deeply, buds will sprout from the cut surface, so it was necessary to cut them accurately, but with conventional devices it is possible to cut bent leeks at the correct cutting location. It was almost impossible.

[0018]
In order to use the leek cutting machine 1 of this embodiment, first, the motors 21 and 22 are operated so that the rotary blades 19 and 20 can be cut, and the motor 26 in the apparatus frame 25 is operated, The driving roller 3 is rotated to move the belt conveyor 2. The endless V-belts 6 and 7 of the pressing means are simultaneously driven by the pulley 12a of the rotary shaft 13 that rotates synchronously via the gears 28 and 29, and moves at the same speed in the same direction as the belt conveyor 2, and further the belt conveyor 2 The rotation of the driven pulley 4 is transmitted to the guide pulley 16 by the endless V belt 18, and the endless flat belt 15 also moves at the same speed in the same direction as the belt conveyor 2. In a state where cutting and transporting are possible, the operator picks up the leek 33 placed on the supply table 30, and straightens the needle 15b so that the root of the leek 33 is perpendicular to the belt surface 15a of the endless flat belt 15. The leeks 33 are placed one by one on the belt conveyor 2 one after another while being stabbed into the root 33b of the root 33a that has been stabbed and hard so that the needle 15b passes. In the state where the root 33b of the root 33a of the leek 33 is held by the needle 15b, the optimal cutting point 33c at the base, that is, the position of d2 = 2 to 3 mm stem side from the root 33b of the root 33a is just the cutting surface of the rotary blade 19 Since the positional relationship between the rotary blade 19 and the endless flat belt 15 and the length of the needle 15b are set so as to coincide with 19a, it corresponds to a position where the leek 33 can be cut correctly easily only by the operation of inserting the leek 33 into the needle 15b. (See FIG. 5). The endless flat belt 15 moves at the same speed as the belt conveyor 2 and is conveyed while the state where the leeks 33 are inserted into the needles 15b is maintained. The leeks 33 enter under the endless V-belts 6 and 7 together with the belt conveyor 2 and are held by the belt conveyor 2 and the endless V-belts 6 and 7 that move at the same speed. When the end 15 of the belt 15 is reached, the endless flat belt 15 returns and the needle 15b moves away from the conveying direction of the belt conveyor 2, but the leeks 33 are held by the endless V belt 6 and the belt conveyor 2 toward the needle 15b. Without moving, the needle 15b comes off the root 33b of the root 33a of the leek 33 and leaves. When the leek 33 is held between the endless V belts 6 and 7 and the belt conveyor 2 and proceeds to the front of the rotary blades 19 and 20, a pressing force is applied by the press pulleys 8 and 9, and the endless V belts 6 and 7 and the belt In a state where the holding force of the leeks 33 between the conveyors 2 is further increased, the rotary blades 19 and 20 are reached and both ends 34 are cut and separated. By increasing the holding force by the presser pulleys 8 and 9, the leeks 33 are not moved by the rotational force of the rotary blades 19 and 20, but can be cut at right angles as they are. After cutting, the green onions 33 are conveyed as they are on the belt conveyor 2, are carried out from the carry-out side, and gather on the chute 31. The cut end 34 is discharged through the discharge guides 23 and 24.
